Needle hydrophones range

Recommended for use in measurements of high-pressure fields above 40 MHz.

Recommended for use in high-frequency, high-pressure fields to minimise the effect of spatial averaging.

With a good signal-to-noise ratio, the use of this device is recommended in most measurement situations to minimise the effect of spatial averaging.

Hydrophones of 0.5 mm have been widely used in the measurement of high-frequency ultrasound.

This probe has outstanding sensitivity and is ideally suited to the measurement of lower frequency fields.

A waterproofed miniature broadband attenuator intended for use in the Precision Acoustics’ HP hydrophone system in order to extend the upper limit of detector dynamic range.

Provides DC power to the submersible preamplifier whilst at the same time acting as an acoustic signal coupler between the preamplifier and the user’s measurement system (via a hydrophone booster amplifier, if used).

The submersible preamplifier is an essential part of the hydrophone signal as it buffers the signal and provides a 50 Ω source. It connects either directly to an interchangeable probe (‘HP’ series), or, if required, via a 20 dB in-line attenuator (A20/1).
